COMBINED GRAIN-DOOR STRI AND SIDE-DOOR-POS'I PROTECTOR.

Application filed April 7,

The invention relates to a combination box car grain door strip and side door post protector.

The object of the invention. is to provide a simple, practical and efficient combination grain door strip and side door post protector of strong, durable and comparativ'ely inexpensive construction adapted to be readily applied to a box car .interiorly thereof at opposite sides of the door opening and equipped with a metal housing adapted to protect the side post of boxcars and also to support a wooden strip n position for enabling the boards of a grain door to be secured to it without the nails or other fastening means penerating the side post of the car.

Anotherobject oft-he invention is to pro vide a combined grain door strip and door post protector adapted to last the full life of a box car and capable of enabling the wooden stri which-receives the fastening devices of tlie grain door to be readily replaced when necessary and capable of bracing and supporting the wooden strip at opposite sites thereof and of enab ng the wooden .strip to last for a considerable length of time so that it will not require renewal until .the box car is overhauled or rebuilt.

trucks or other objects.-

lVith these and other objects in view, the invention consists in the construction and novel combination and arrangement of parts hereafter fully described, illustrated in the accompanying drawings and pointed out in the claim hereto appended, it being understood that various changes in the form, proportion and minor details of construction, within the scope of the claim, may be resorted towithout departing from the spirit or sacrificing any of the advantages of the invention. v

In the drawings Figure 1 is a-=longitudinal sectional View of a portion of a car showing one of the I side doors thereof in elevation equipped e ceives a wood filler stri 1926. Serial No. 100,466.

with combined grain door strips and side post protectors constructed in accordance with this invention.

Fig. 2 is a central longitudinal sectional:

the grain door strip being broken away to enable it to be shown on a larger scale.

Fig.3 is a transverse sectional view of the grain door strip and side post protector taken on the line of Fig. 2.

1n the accompanying drawing in which is illustrated the preferred embodiment of the invention the combined grain door strip and side post protector'con-sists of a metallic housing constructed of any suitable metal and composed of spaced side bars 1 and intogral connecting transverse bars or portions 2 arranged at the-ends of the center of the metallic housing as clearly illustrated in Fig. 2 of the drawing but any desired number of the integral Connecting cross pieces 2 may of course be employed as will be readily understood. The side bars 1 of the metallic housing are substantially quadrant shaped in cross section to present flat inner and rear faces 3 and 4 and smooth rounded surfaces 5 at the exposed corner portions as clearly illustrated in Figs. 3 and at of the drawings. The said sidebars may be made of any desired size and are preferably castings and may be made either solid as-shown or cored. out to provide a hollow relatively light contraction where desired. The metallic housing is'secured to the interior of the car 6 at opposite sides of the door opening 7 by screws 8 which have their heads arranged in flush relation with the outer faces of the side bars of the metallic housing. bars are provided with openings 9 which have enlarged tapered outer portions 10 to permit the heads of the screws to be countersunk in the side bars of the metallic strip. The grain door strip and side post protec- The side tor extends from thetop to .the bottom of the door opening 7 as clearly shown in Fig.

1 and it may be made of any desired dimensions as will be readily understood.

The spaced or longitudinal openingin the metallic housing between the side bars 1 re- 11 rectangular in cross section as clearly s own in Figs. 3 and 4 of the drawing and provided at its ends and center with recesses 12 and 13 for the reception of the cross pieces of tlie metallic housing whereby the wood filler strip is interlocked with the metallic housing. The wood filler strip extends from the front faces of the side bars 1 to the rear faces thereof except that the recesses 12 and 13 for the reception of the cross pieces '2 and the na ls 14: or other fastening devices for securing the boards 15 of the grain door to the sides of the car are driven into the wood filler strip. By securing the grain door to the wood filler strip the side posts are protected from the fastening devices of the grain doorvand the latter may be removed without injuring the door posts or sides of the car and the wood filler strips may be used repeatedly and will last until the Car requires rebuilding or overhauling. tallic housing may be constructed to receive a wood filler strip of any desired dimens ons and while for convenience of illustration the boards 15 of the grain door are shown covering only the lower halfof the door opening 7 it will be clear that the grain door strip will enable the boards to be extended upwardly from the bottom of the car as far as desired. The device is adapted to protect the door posts and the sides of the car at the door opening and will materially increase the life of the. car and will lessen ex- The me pense of handling grain by avoiding the injury which ordinarily results from the use of grain doors of the ordinary construction and from the contact of hand trucks and other objects with the door posts.

What I claim is j A combined grain door strip and side door post protector locatedinteriorlyof the car at opposite sides of the door opening and comprising a metallic housing composed of spaced longitudinal side bars andintegral cross pieces connecting theside bars and arranged in flush relation with the rear face thereof, the side bars being provided with openings for fastening devices for securing I the metallic housing to the car, said side bars presenting smooth rounded surfaces at the front exposed corners, and a wood filler strip fitting and filling the space between the side bars and provided at its inner or rear face with recesses conforming to the configuration of and receiving the said cross pieces whereby the filler strip is interlocked with the metallic housing, said filler strip be ng arranged to receive the fastening devices of a grain door.

In testimnoy whereof I have hereunto set my hand. 1
